How does one encode a movie clip that can be played back with quicktime player.

Here is what I got so far working:

gst-launch -e videotestsrc do-timestamp=1 ! video/x-raw-yuv, width=640,height=480,framerate=30/1 !
videorate ! queue ! ffenc_mpeg4 bitrate=1500000 name=venc   alsasrc do-timestamp=1 !
audio/x-raw-int,rate=48000,channels=2 ! queue ! audioconvert ! faac bitrate=128000 name=aenc   qtmux
name=mux ! filesink location=vidtst_2.mp4 aenc. ! mux. venc. ! mux.

I can open it with Quicktime player, but I only hear the audio. Video is just blank (black).

Audio and video plays back fine though with mplayer and vlc.

What does it take to support Quicktime Player?

Any pointers are appreciated.
